The true statement about the function of area of by rectangle and width of rectangle are:

The correct answer option is options A and D

A rectangle is a quadrilateral having opposing sides parallel and four right angles.

At point (x, y) = (10, 100) the area is maximum.

This means that the area of the rectangle is maximum when width is 10m.

If the width of the rectangle is more than 10m, the area reduces or decreases.

Therefore, the statement Greater width relates to greater area as long as the width is more than 10 m is false.

The statement "To get the greatest area, the width should be 20" is false.

Answer:

Step-by-step explanation:

Answer:

  -425

Step-by-step explanation:

You want the sum of the first 8 terms of the geometric series with first term 5 and common ratio -2.

The sum is given by the formula ...

  Sn = a1·(r^n -1)/(r -1) . . . . . . a1 = first term, r = common ratio

The sum of 8 terms of the given series is ...

  S8 = 5·((-2)^8 -1)/(-2 -1) = 5(255/-3) = -1275/3 = -425

The sum of 8 terms is -425.

Answer: It will take 24 years to have 7 million.

Step-by-step explanation:

1.65% of 5.04 million is 83,160.

2018 is 6 years from 2012.

83,160 x 6 = 498,960.

498,960k + 5,040,000mil =5,538,960mil. still not quite 7 million.

498,960k x 4 = 1,995,840mil.

1,995,840mil + 5,040,000mil = 7,035,840mil.

It will take the city 24 years to have 7 million.

Using multiplication or division, we can have either of the numbers from the operation.

multiplication is the repeated addition of numbers. But the rules for multiplication of integers are different from that of addition. It includes three possibilities. They are:

The product of two integers with similar sign numbers will always be positive. This means the product of two positive numbers or two negative numbers will always be positive. While the product of a positive number and a negative number (integers with different signs) will always be negative.

In this case, the three numbers are interconnected via arithmetic operation.

135 ÷ 15 = 9

9 × 15 = 135

135 ÷ 9 = 15

So, which ever way we go with, these numbers are connected to each other.

At that particular critical point, the second derivative needs to be negative in order to obtain the dimensions of the cylinder with the maximum volume. The values of the function that contain both variables are then substituted to obtain the dimensions.

A right circular cone with a height of 2.5 and a base radius of 7.5 inscribes the given cylinder.

Assume that h is the height and r is the radius of the cylinder. Using triangles that are similar, express h in terms of r as follows:

2.5/7.5 = 2.5-h/r

2.5r = 18.75 x 7.5 x 2.5 h = 2.5 x 1/3r

V= πr²h is the formula for the cylinder's volume.

As a result, only write the volume in terms of r.

V= r2h V= r2(2.5-1/3r)

V= 2.5πr² - 1/3πr³

As a result, the cylinder must have dimensions of r=5 and h=0.83.

Answer:

a) 6.2%
b) £13,687

Step-by-step explanation:

a)

To find the rate of interest, we first find the interest itself.
£7965.00 - £7500.00 = £465.00
Using this, we find the rate of interest in percentage as a fraction of the original loan.

(£7500.00 ÷ £465.0) × 100 = 6.2%

Thus, the rate of interest is 6.2%.

b)
Compound interest is found using the formula
[tex]A = P(1 + \frac{r}{100})^{t}[/tex]
Where

A = final amount

P = initial principal balance

r = interest rate

t = number of time periods elapsed

Thus, with an initial balance of £7500, an interest rate of 6.2% and a time period of 10 years, calculated per annum, we can plug the numbers into the formula, giving us

[tex]A = 7500(1 + \frac{6.2}{100})^{10}[/tex]
   [tex]=[/tex] £13,686.94
   ≈ £13,687 (to nearest £1)

Some things to note: number of time periods elapsed mean the amount of times it is compounded; if the question says compounded quarterly for 3 years, t = 12 as it is compounded 4 times a year for 3 years, giving is 12 time periods. This also applies to monthly, bi-weekly etc.

The measure of angle 4 is 125° for the given triangle.

According to the question,

We have the following information:

A figure is given of triangle and its exterior angles.

m∠1 = 70°

Now, the two sides (with line on them) of the triangle are equal. So, it means that it is an isosceles triangle.

We know that sum of three angles of a triangle is 180°.

Let's take the two equal angles to be x°.

x+x+70 = 180

2x+70 = 180

2x = 180-70

2x = 110

x = 110/2

x = 55°

We know that angles made on a straight line is 180°.

∠4 and angle x will make a straight line.

∠4 = 180-55

∠4 = 125°

Hence, the correct option is A.

Answer:

x = 154

Step-by-step explanation:

[tex]\frac{x}{11}[/tex] + 16 = 30 ( subtract 16 from both sides )

[tex]\frac{x}{11}[/tex] = 14 ( multiply both sides by 11 to clear the fraction )

x = 11 × 14 = 154

Answer:

x = 154

Step-by-step explanation:

Given equation,

→ (x/11) + 16 = 30

Now the value of x will be,

→ (x/11) + 16 = 30

→ x/11 = 30 - 16

→ x = 14 × 11

→ [ x = 154 ]
